Many important processes in chemistry and biology occur in the solution phase, including protein conformational changes, energy transfer processes, and proton and electron transfer reactions. Understanding condensed phase dynamics on ultrafast timescales is essential for describing and predicting these processes, which is why it is a prevailing topic throughout the scientific community. In this talk I will discuss two different research topics that explore different processes in condensed phase systems. The first focuses on investigating the photophysics of BODIPY based chromophores. BODIPY chromophores have a wide range of applications spanning biological imaging to artificial photosynthetic light harvesting. Here we have applied two-dimensional electronic spectroscopy (2DES) to BODIPY based chromophores to (1) reveal ultrafast solvation dynamics and (2) to characterize their Franck-Condon active vibrational modes. The second topic investigates the confined dynamics of fluxional metal-carbonyl complexes encapsulated by Pd<sub>6</sub>L<sub>4 </sub>nanocages through applying polarization dependent mid-IR pump-probe spectroscopy and two-dimensional infrared (2DIR) spectroscopy.
